Did you ever compare these to the KEF s that you mentioned? Very curious.
No, sadly I didn't. It's been a long time since I sold these speakers. I always look out for Genesis speakers on Craigslist, Facebook marketplace etc. Sadly, a lot of people think old speakers improve with age like wine, and so want crazy prices for ones that need fixing. The ones in this thread, I think I paid $20 for them. The cost of "genuine" foams for the woofer and passive radiators easily exceeded that. And if I put a price on my time, I probably only broke even when I sold them.
The problem when comparing speakers is their relative efficiency. The KEFs would be less efficient than the Genesis. I always wanted to build a semi-active speaker switch, whereby it accounts for the different efficiencies of the speakers you have hooked up.
